Grams per watt

Ah the little piggies , how they snort n they grunt ....
I will admit, that I’ve yet to brake 2gpw , but I’m dealing with limited head room.
I have broke 1.9 so 2 is possible

Understanding cause & affect goes a long ways .
Just drop a brick... respect ganjababa let me know how much time u passed in veg stage and whoa what a stretch why tall and thin mostly preferred small bushy ones and why hps why do u prefer it im just curious

Usually it’s 8 weeks of veg , sometimes could be an extra week if I’m waiting for a spot to open. That could be shorten with adding co2. I only gas in flower.
When trying to manipulate yields, a plant that stretches a lot in flower will out produce one that stays short , they just make more nodes .
But this is all relative to space & plant count & work. I would rather take 1gpw or a bit better in a SOG then growing low count trees, but I have to follow rules for my license.
The DE HPS has the best penetration, with proper training n pruning I can make a cube of bud not just a canopy.
Some people think in the lines of ....
“Think chest not checkers , if your thinking this way, it’s still 2D , think house of cards , n keep everything balanced in 3D .

If this is the case how are the 2 light sources any different in actual yield? Look at the bud factory yield, dude veg for 3 months and forgot to mention that being a major factor in their yield. Now look at renfro's garden, huge veg with huge yields and its a different light then the bud factory light. The same equipment are being used other than lights. I see splits all over the place now a days.
I don't know the bud factory guy and I'm not going to look him up. Obviously there is a point where vegging will eat into cycles per year but if anybody is unhappy with their yield and doing short veg cycles I would encourage them to veg for another week and see what happens. Generally speaking the strain and style dictate how long I veg.

So it's not hard if you are an extremely good and knowledgeable grower ;) Perhaps it's not hard when one is on that level, but how many are?

This level of grower is not so far from beginner then you think, although it does require either being autocratic and very objective or some form of mentorship but you should be able to learn all the knowledge required by your forst harvest if you start from seed...one cycle is more then enough time...

Wait you said if you adding co2 during veg period it’ll be short plant and mean less yields ? One more question you mean when we compare same wattage hps and smd led is hps better

I would be able to shorten the veg period if I added co2 . It would make bigger plants not smaller.

I’m saying a double ended hps has enough intensity to out do LEDs, if you are able to control the environment.

If your referring to my grow, that veg only took that long because Cornbread are squat fucks that too forever in veg due to the bubba kush lineage. Which is why I'm not growing them again. Now my ghost train haze only needs a month to a month and a half, which I know are bigger yeilders. The stretch is insane. Like 3 to 3.5x. I'm doing those clone under the LED for the first time. I'll post soon enough.

I know that, I wasn't being negative on your grow. Your garden is outstanding! I was only trying to point out veg time and genetics play a huge roll in what you guys are claiming is the king of all measurements (GPW). Where i live no one cares how much someone yields, if your quality isn't on point the guy down the street has you smashed.

I'm using gavitas for most of my grows but I do have a quantum board grow, initial layout for the lights was more expensive but I'm reaching a similar yield for less power and it's he'll of a lot easier maintaining the environment. Ime hps gives more yield for your buck but technology gets cheaper each year and in the end led will take over as the best lights to grow with.bud quality is for the most part better from led than hps but this seems to be from the more stable temperatures and it's not a huge difference but a slight one

Yeah, because people lie and post pics to prove it. He says he got 1.9 I believe it, bud looks fine, not all strains are the same.

2 GPW is possible with HPS
It is possible, and I have seen it, but that was in an aeroponic stadium (vertical HPS grow) – I have never seen 2gpw under hooded (horizontal) HPS lamps - even with CO2. Best I ever got was 1.4gpw using 1200W of vertical HPS in coco, no CO2, and this is typically what my plants looked like. This one was 12oz.

Here are four plants, including the one above (far left), hanging up to dry. Each peg is a different plant:




Veg time is a bullshit metric. It only makes a difference if you are not vegging long enough for your grow area and lighting. If you overveg, you end up with the same yield or less. There is a point of equilibrium that is a function of light vs canopy volume beyond which veg time makes no difference. If you think about it, you can't veg a plant bigger than your flowering area and lighting set-up, so at some point extra veg time becomes counter-productive.

Hey. I'm a bit confused on what to believe. So a hps set up can pull 0.5 g per watt and a good led can pull 1 - 1.5 or even 2g per watt. Is this true has anyone had results that prove this?. If I use a 600 hps I'll get 300g but if I used a 300 true watt led I cound get 600g or even more ?. Seems abit to good to be true.
sort of true. a well managed HPS garden with t he right strain can easily pull over 1 GPW and a poorly managed LED garden with a low-yielding strain can pull under 1gpw

if you are getting 300g with a SE HPS, id expect 400 or so with the best LED and same technique
